yeah shaun, you are rigth. After follow your sugestion i searched in
the docs and found what you mean here:
http://livedocs.adobe.com/flex/201/langref/package.html#Boolean()
Boolean its a function that have the same behavior than the Boolean
constructor that take a non-empty string and convert it to "true".
aww.
very weird.
anyway thank you and the others to help understand what is going on here.
now i will try to minimize the damages :)
[]'s,
Luís Eduardo.
